Made this an independent day trip after too lazy to do from S Sis day before. Left Pole Creek TH @ 9.46.

Scree slogging along with intermittent snow crossings & occasional enjoyable scrambling took me to the summit (which I had all to myself) at 14.49. Enjoyed a Deschutes Twilight ale & herbal supplement. Relished doing my last Sister while somewhat sad that I was done with them. Very cool that I saw no-one else on mountain! While a bit hazy, views phenomenal- saw next volcano past Hood (Adams?!). Hundreds of butterflies flying over summit again- very cool!

Hurried down at 15.49 after discerning what appeared to be a storm cloud forming over S Sister (& moving my way; it later dispersed). Lengthy descent after took dfft route down, ending up too far (skier's) R & needing to traverse back over. Some fun glissading (& one short self arrest where slipped on ice beneath snow) & a few short but nervous (smaller) glacier crossings (where they were narrow & slopes appeared concave) & I was back to the trail. Back at TH/car at 19.54. Great day to be alive.

As a side note, Sisters' glaciers had a lot more snow covering them than those on Shasta's N side.

Dad, brother Jon, and I did the day hike from Frog Camp in the summer of 1963. After looking at this from Mt Bachelor since the days of just a rope tow and a pomalift at the ski area, we finally came over and climbed one of the most beautiful volcanic mountain groupings in the world -- 3 Sisters + Broken Top

I was summitpost surfing and came across your summit log. It is so true the walk out on the Obsidian trail is long. It's the last miles of featureless forest after lava flow that lulls one into hullucination. I reminised and had to laugh,

Beautiful weather up there for my 4th summit of Middle. The snow pack was super high this year and we ran into almost continuous snow from 5500' on up. The snow was perfect and held up all day so that there was no postholing. The snowfield up at the base of the North Ridge was very steep this year. Fortuatley the snow was perfect for kicking steps that did not blow out. Had probably the best glisade coming down ever.

Took the easy way and spent the night at 7000' (tree line). Easy non tech slog to the saddle. Saw the crevasses on both sides of the snow ridge. The crampons came off at the saddle due to the exposed scree slope on the north side until we hit the most difficult part of the climb. A 50 deg. snow patch about 150' high. Not too bad though. It was tougher down climbing than going up. 74 deg warm at the summit. Awesome views as far north as Adams, pretty dirty looking west, and South Sister w/ Broken Top looked beautiful as ever. The 5 miles back from camp in the heat was the least enjoyable part of the trip. The bugs were hungry....

On August 15, 2003 a friend of mine was hiking to the top of this mountain when he fell to his death. One year later, a small group of us finished the climb in his memory. With us we carried an orange ribbon in his honor (orange was his favorite color). The climb was beautiful and the view amazing. God is good.

The climb began on saturday the 2nd of july at pole creek trailhead. Myself and seven other fellow obsidian club members participated. The obsidians are a climbing and hiking club located in Eugene, oregon. It was one of the first hot days of summer in the cascades. We had a leisurly and uneventful hike in to base camp. We pitched our tents along some springs just a couple hundred yards below the snout of the Hayden glaicer at about 7000 ft. We awoke at 3:30 in the morning to a star choked sky and unusually warm morning. We throw are gear together donned are packs and headed for the glacier. We arrived at the glacier and proceeded to flake out the rope,slip on harnesses and fit crampons on boots. With two rope teams of four we proceeded up the right or north side of the glaicer. the route is a high snow cornice that runs parellel along the glacier well above the visible crevasse fields. The cornice peters out just below the peak known as prouty. Once off the cornice we walked a short distance to the col are the saddle. We all take turns belaying the next person to us over the mote and onto the rock. We repeat this procedure as we head onto the snowfield at the base of the summit pyramid. The final pitches to the summit do not lay back all that much so we set two pickets along the steepest sections and eventually work are way through frozen rock and rotten ice/snow mix. We arrive at the sun splashed summit at 7:30 in the morning. We enjoy views all the way north to Mount adams in Washinton state. west to the coast ranges south to mt Mcgloughlin and were a bit blinded by the sun as we look to the east on oregons great high desert plateau.

This was little more than a walk-up but a very nice one at that. The Collier Glacier presents little in the way of challenges now as it no longer has any crevasses (contrary to the trip report from 2001 commenting on a lot of crevasses on it's northernmost side -- and our President claims Global Warming is no big deal...). Crampons are stil necessary, particularly early in the morning in late season, as the ice is firm and footing would be very difficult without them.
